Subject: [PATCH v8 00/10] Genericize DW MIPI DSI bridge and add i.MX 6 driver

Hello everyone,

The dt-binding added in this series depends on [1] for
"make dt_binding_check" to pass.

The biggest change in v8 is a conversion of the imx6 host controller
driver to drm_bridge and an extension to dw_mipi_dsi.c which allows
platform drivers to daisy-chain bridges between the encoder and the
Synopsis DSI bridge.

Obviously a lot more work can be done on this front, for example to
convert the Rockchip and STM platform drivers to drm_bridge (the STM
driver doesn't even use the current dw_mipi_dsi.c bind API to attach)
or to improve the API itself.

Another kind of related work is refactoring the existng IMX drivers
to drm_bridge and move the empty encoder management to imx-drm-core.

Because this patch is already quite big, I did only the minimum
changes to get the imx6 mipi dsi driver in good shape, all the other
changes should be done in separate patch series.

I also just realized imx6qdl.dtsi was missing some properties to get
the DSI host controller working so I've added them as a new patch.

All received feedback up to this point has been addressed.

Thank you and best wishes,
Adrian
